Take it to the limit : Parent acenes larger than heptacene have eluded synthesis for decades. When 1,2‐diketone bridges in suitably designed tetraketone precursors were removed by irradiation under matrix‐isolation conditions (see scheme), the parent systems of the two next higher acenes were accessible experimentally.
